LINCO steel & cast iron wheels are a great solution for a caster wheel in an abusive and abrasive environment such as in many industrial environments. Our cast iron wheels have an exceptionally long wear life as they are made of a material that literally wears like steel. Industrial cast iron wheels are preferred in a heavy duty setting not only for their longevity and strength, but also are sought after for their ability to withstand and transport very heavy loads without forfeiting maneuverability.
